Description

The present invention relates to a metered dose aerosol product.

Patent Document 1 describes an aerosol product that gives a feeling of cooling effect to a user in addition to the medicinal effect by increasing the injection sound.

JP 2012-115792 A

By the way, in recent years, the concentration of contents has been increased in order to reduce the size of products. Since such an aerosol product can obtain the same effect and effect with a smaller usage amount as compared with the conventional product, the amount of the content to be sprayed is smaller than that of the conventional product when the spray is performed as prescribed. .. For this reason, the user may feel unsatisfactory, and there is a risk of causing excessive use, such as ejecting more than necessary.

In the aerosol product disclosed in Patent Document 1, since the injection sound is increased, it is considered that a feeling of use can be obtained as compared with a case where the content is simply injected.
However, the aerosol product of Patent Document 1 produces an injection sound by passing an aerosol composition containing a liquefied gas through a fine particle generation part having a specific inner diameter and length, and a desired injection sound is obtained. Therefore, a large amount of aerosol composition is required, and there is room for improvement from the viewpoint of suppressing overuse.

Therefore, it is an object of the present invention to provide an aerosol product that gives a feeling of use even with a small injection amount.

The aerosol product of the present invention includes an aerosol container filled with contents, a metering unit that is mounted on a valve of the aerosol container, temporarily blocks communication with the outside, and stores a predetermined amount of content, and a metering unit. It is characterized in that it is provided with a sounding means which emits a sound when releasing the stored contents.

It is preferable that the sounding means emits sound by releasing the elastic piece elastically deformed by a storage operation for storing the content in the fixed quantity unit or a releasing operation for releasing the content stored in the fixed quantity unit. ..

Alternatively, the sounding means stores the content consisting of an emulsion obtained by emulsifying an aqueous stock solution containing a surfactant and a liquefied gas in a quantitative unit, vaporizes at least a part of the liquefied gas in the quantitative unit, and performs a release operation. Therefore, it is preferable that the emulsified product in the quantitative unit is emitted to the outside to produce a sound.

Since the aerosol device of the present invention is provided with the sounding means that emits a sound when releasing the content stored in the fixed amount unit, it is possible to obtain a feeling of use as compared with the case where the content is simply jetted (released). , It is possible to suppress overuse. Moreover, since it is combined with the metering unit, overuse due to continuous injection can be suppressed.

In addition, if the sounding means emits sound by releasing the elastically deformed elastic piece, it is possible to feel shock and vibration along with the sound, or to visually recognize a change in the shape, so it is said to be ejected. Easy to get satisfaction.

Further, the sounding means stores the content of an emulsion obtained by emulsifying an aqueous stock solution containing a surfactant and a liquefied gas in a quantitative unit, vaporizes at least a part of the liquefied gas in the quantitative unit, and performs a release operation. Therefore, if it is pronounced by injecting the emulsion in the quantitative unit to the outside, the liquefied gas vaporized in the quantitative unit causes a turbulent flow when the emulsion in the quantitative unit passes through the injection hole. Sound is emitted and the momentum of the injection becomes stronger, making it easier to obtain the satisfaction of the injection.

It is a schematic sectional drawing for demonstrating the mechanism of fixed quantity injection. It is a figure which shows the process of the injection operation of the aerosol product shown in FIG. FIG. 3 is a cross-sectional view showing a different embodiment of the aerosol product of the present invention. It is a schematic sectional drawing which shows another embodiment of the aerosol product of this invention.

Next, the aerosol product 1 of the present invention will be described in detail with reference to the drawings. An aerosol product 1 shown in FIGS. 1a and 1b is an aerosol container 10, a metering unit 20 mounted on the aerosol container 10, an aerosol container 10 and a metering unit 20, and a spraying member for spraying contents. 30 and 30 are provided.

The aerosol container 10 includes a bottomed cylindrical container body 11 having an opening at the upper end, and a valve 12 attached to the upper end of the container body 11. The valve 12 has a disc-shaped mounting cup 13 and a housing 14 attached to the central portion thereof, and the upper surface of the container body 11 is covered with the inner bottom surface of the bead portion of the container body 11. It is fixed by clinching. The container body 11 may be made of metal or synthetic resin.

Reference numeral 15 in FIG. 1c indicates a stem. The stem 15 is of a tilt type and is supported in the housing 14 so as to be vertically movable and tiltable. Specifically, the stem 15 includes a cylindrical stem upper portion 15a, a columnar stem lower portion 15b, and an annular flange portion 15c provided therebetween and protruding outward. The outer diameter of the flange portion 15c is smaller than the columnar space 14a in the housing 14 and can be tilted in the housing 14. The stem 15 is in contact with the spring 16 on the lower surface of the flange portion 15c, and receives the upward biasing force of the spring 16. The stem 15 is fixed by the mounting cup 13 receiving the force. Further, the stem lower portion 15b is fitted with the spring 16, so that the elasticity of the spring 16 helps the stem 15 to return to the upright position. Further, the upper surface of the flange portion 15c is recessed in a mortar shape, and a stem hole 15d is formed at the base of the stem upper portion 15a rising from the lowest point of the recess. Further, the stem rubber 17 is fitted over the stem hole 15d of the stem upper portion 15a, and in the steady state, the outer peripheral edge of the upper surface of the flange portion 15c is pressed against the lower surface of the stem rubber 17 to close the stem hole 15d. .. In the present embodiment, until the stem 15 is tilted to a predetermined angle or pushed in by a predetermined amount, no gap can be formed between the outer peripheral edge of the flange portion 15c of the stem 15 and the lower surface of the stem rubber 17 (the stem hole 15d. To maintain the blockage condition), "play" is provided. As the "play", for example, it is conceivable that the outer peripheral edge of the upper surface of the flange portion 15c is fitted into the lower surface of the stem rubber 17 in a steady state. The metering unit 20 is attached to the upper end of the stem 15.

The metering unit 20 is for temporarily storing a predetermined amount of contents, and as shown in FIG. 2, a valve seat 21 attached to the upper end of the stem 15, and a valve seat 21 attached to the valve seat 21. It is composed of a lower plate 22 and an upper lid 23 fitted on the upper end of the lower plate 22.

The valve seat 21 has a cylindrical shape having an upper bottom 21a, and a communication hole 21b is formed on the side surface. Further, a flange portion 21c protruding outward in the radial direction is formed at the lower end portion.

The lower plate 22 has a cylindrical shape with a bottom, and an insertion hole 22b is formed in the center of the bottom 22a. The lower side of the insertion hole 22b is enlarged, and the stepped portion 22c generated by the enlarged diameter is engaged with and supported by the flange portion 21c of the valve seat 21. An upper lid 23 is fitted on the upper end of the cylindrical side wall 22d so as to be vertically slidable.

The upper lid 23 has a cylindrical shape having an upper bottom 23a. A communication hole 23b is formed in the center of the upper bottom 23a, and an engagement cylinder 23c is formed by extending the hole wall of the communication hole 23b upward. The injection nozzle 33 is attached to the engagement cylinder 23c.

As shown in FIG. 2a, in the steady state unit 20 having the above-described configuration, in a steady state, a gap is formed between the lower surface of the upper bottom 23a of the upper lid 23 and the upper surface of the upper bottom 21a of the valve seat 21 to communicate with the outside. 2B, the upper lid 23 is moved downward so that the lower surface of the upper bottom 23a of the upper lid 23 and the upper surface of the upper bottom 21a of the valve seat 21 are brought into contact with each other, as shown in FIG. 2B. The communication hole 23b is closed (sealed), and the outer peripheral surface of the valve seat 21 and the inner peripheral surfaces of the lower plate 22 and the upper lid 23 form a closed space (quantitative chamber) E. The downward movement of the upper lid 23 is performed by using the ejection member 30 described below.

As shown in FIG. 1b, the injection member 30 includes a main body 31 attached to the upper portion of the aerosol container 10, an operation lever 32 for performing an injection operation of the contents, and an injection nozzle 33 attached to the metering unit 20. It is composed of

The main body 31 has a cylindrical shape having an upper bottom 31a. A guide part 31b for guiding the metering unit 20 is provided on the inner periphery on the right side in FIG. 1b. A support shaft 31c for supporting the operation lever 32 is provided on the left side in FIG. 1b at the upper end of the main body 31. A cutout 31d (see FIG. 1a) is provided so as to avoid the operation lever 32.

The operation lever 32 has one end rotatably supported by the support shaft 31c. The other end is provided on the right side in FIG. 1b so as to project outside the container body 11. The operation lever 32 is provided with an insertion hole 32a at the center thereof, and the injection nozzle 33 projects outward from the insertion hole 32a. In addition, a pressing protrusion (elastic piece) 32b extending downward is provided on the lower surface side.

As shown in FIG. 1b, the injection nozzle 33 is composed of a cylindrical portion 34 for guiding the contents to the outside and a base portion 35 provided at the lower end portion thereof. The base portion 35 has a substantially cylindrical shape having a larger diameter than the cylindrical portion 34, but a part (on the right side in FIG. 1B) of the base portion 35 projects outward in the radial direction. Is a contact portion 35a. The contact portion 35a is also a portion where the lower portion contacts the guide portion 31b, and is gently inclined toward the inner side as it goes downward. A leaf spring 35b is provided so as to abut on the inner peripheral surface of the main body 31 from the side opposite to the contact portion 35a (left side in FIG. 1b).

In the aerosol product 1 having the above configuration, a predetermined amount of content is ejected by the ejection operation of operating the operation lever 32. The injection operation is roughly classified into a storage operation of temporarily storing the contents in the fixed amount unit 20 and a releasing operation of releasing the contents stored in the fixed amount unit 20. The mechanism will be described below.

Before the operation lever 32 is operated, as shown in FIG. 3A, the tip of the pressing protrusion 32b of the operation lever 32 is in contact with the upper end of the contact portion 35a of the injection nozzle 33. Further, the ejection nozzle 33 is in an upright state by the leaf spring 35b and the guide portion 31b. Since the pressing protrusion 32b is for pushing the injection nozzle 33, the pressing protrusion 32b may be formed so as to abut on a portion other than the abutting portion 35a.

When the operation lever 32 is rotated downward about the support shaft 31c, the ejection nozzle 33 is pushed downward by the pressing protrusion 32b of the operation lever 32, as shown in FIG. 3b. At this time, since the stem 15 is a tilt type and the direction in which it can be moved is restricted by the guide portion 31b, the jet nozzle 33 and the metering unit 20 are resisted by the urging force of the leaf spring 35b as they descend. It is in a slightly inclined state (when the support shaft 31c side is the front side and the other end side of the operation lever 32 is the rear side, the state is inclined forward).

In this state, in the metering unit 20, as the injection nozzle 33 is pressed, the upper lid 23 is also pressed, and the lower surface of the upper bottom 23a of the upper lid 23 and the upper surface of the upper bottom 21a of the valve seat 21 come into contact with each other to form the metering chamber E. To be done. Further, since the stem 15 is also inclined and descends via the metering unit 20, a gap is formed between the outer peripheral edge of the flange portion 15c of the stem 15 and the lower surface of the stem rubber 17, and the blockage of the stem hole 15d is released, resulting in a valve seat. The content in the aerosol container is supplied into the fixed amount chamber E through the communication hole 21b of 21 and the content is stored in the fixed amount chamber E (see FIG. 2b: storage step). At this point, the pressing protrusion 32b continues to press the contact portion 35a while elastically deforming itself, and keeps the storage state in which the constant amount chamber E of the constant amount unit 20 is filled with the contents.

As the operating lever 32 is further pushed in here, the inclination of the injection nozzle 33 increases, and the pressing protrusion 32b of the operating lever 32 gets over the contact portion 35a of the base 35, as shown in FIG. 3c. At this time, the contact portion 35a is repelled by the pressing protrusion 32b (the pressing protrusion 32b is repelled by the contact portion 35a), so that vibration and sound are generated. It can be said that this state is that the pressing protrusion 32b, which has been elastically deformed by the pushing of the operation lever 32, is vigorously released (disengaged).

At the stage where the pressing protrusion 32b has passed over the contact portion 35a, the downward pressing by the pressing protrusion 32b is released, so that the tilting or pushing of the stem 15 is corrected by the biasing force of the spring 16, as shown in FIG. 3d. The stem rubber 15 closes the stem hole 15d again. Note that in Figure 3d, the stem 15 is still tilted, but this is within the "play" range. Further, the upper lid 23 of the fixed quantity unit 20 rises due to the pressure of the contents stored in the fixed quantity chamber E, the contact between the valve seat 21 and the upper lid 23 is released, and the contents stored in the fixed quantity chamber E are removed. After being released, the content is ejected to the outside from the communication hole 23b of the upper lid 23 through the ejection nozzle 33 (see FIG. 2c: releasing step). When the operation lever 32 is released, the ejection nozzle 33 moves further upward due to the urging force of the spring 16, the upper surface of the base portion 35 of the ejection nozzle 33 contacts the lower surface of the operation lever 32, and pushes up the operation lever 32. At this time, since the injection nozzle 33 is inclined to the side opposite to the pressing protrusion 32b within the range of "play", the pressing protrusion 32b passes over the contact portion 35a and is again positioned above the contact portion 35a. Will be done. After that, the leaf spring 35
The inclination of the injection nozzle 33 is corrected by b, and it returns to the upright state, that is, the state of FIG. 3a. It should be noted that the process of shifting to FIGS. 3b to 3d and the process of returning to FIG. 3a are usually performed in an instant.

As described above, the aerosol product 1 is provided with the sounding means (sounding mechanism) that emits sound almost at the same time as the ejection of the content, that is, the release of the stored content. Therefore, a feeling of use can be obtained as compared with a case where only the contents are jetted. Further, since the sound is emitted by the rapid release (plucking) of the elastic deformation, it is possible to feel the response, the shock, and the vibration through the operation lever 32, and the satisfaction of the ejection can be obtained. Therefore, a sufficient feeling of use can be obtained even with a small amount of 0.01 to 1 ml by the fixed amount unit 20, and as a result, overuse can be suppressed.

FIG. 4 shows a different embodiment of the invention. As shown in FIG. 4A, in the aerosol product 2 according to the present embodiment, the injection member 40 includes a main body 41 attached to the upper portion of the aerosol container 10 and an injection nozzle 42 attached to the metering unit 20. It is different from the above embodiment in points.

As shown in FIG. 4a, the main body 41 has a cylindrical shape, and an engagement hole 41b is provided near the upper end of the side wall 41a. The injection nozzle 42 is composed of a cylindrical portion 43 that guides the contents to the outside and a cylindrical base portion 44 provided at the lower end portion thereof. A part of the side wall 44a of the base portion 44 is divided by slits 44b and 44b (see the arrow A view), and the divided portion (hereinafter, referred to as an elastic piece 44c) has an engagement hole 41b of the main body 41. Is provided with an engaging protrusion 44d. As shown in the figure, the lower surface of the engaging protrusion 44d is inclined and the upper surface thereof is at a right angle.

To inject the contents, first, as shown in FIG. 4B, the injection nozzle 42 is pushed downward to elastically deform the elastic piece 44c of the injection nozzle 42 so that the engagement protrusion 44d is engaged with the main body 41. The hole 41b is engaged. At this time, as described in the previous embodiment, a fixed amount of the content is stored in the fixed amount unit 20 (see FIGS. 2a and 2b: storage operation). This storage state is maintained as long as the engagement protrusion 44d and the engagement hole 41b continue to be engaged. After that, when the elastic piece 44c is elastically deformed by pushing the tip of the engaging protrusion 44d inward, the engagement between the both is released and the injection nozzle 42 rises and is stored in the metering unit 20, as shown in FIG. 4c. As a result of the released contents being released, the contents are ejected to the outside (see FIG. 2c: release operation). At this time, the stem 15 also rises and the stem rubber 17 closes the stem hole 15d again. The sounding is caused by the elastically deformed elastic piece 44c being repelled (the main body 41 being repelled by the elastically deforming elastic piece 44c) as the ejection nozzle 42 rises. In this state, it can be said that the elastically deformed elastic piece 44c is vigorously released (disengaged).

In the present embodiment as well, since the sounding means (sounding mechanism) that sounds at almost the same time as the ejection of the contents is provided, the same operational effect as the above-described embodiment is achieved. In addition, in the case of the present embodiment, since it is possible to visually confirm that the ejection nozzle 42 is moving up vigorously, it is possible to obtain satisfaction that the ejection is performed.

FIG. 5 shows a further different embodiment of the invention. The aerosol product 3 according to the present embodiment is characterized in that it produces a sound by using an emulsion obtained by emulsifying an aqueous stock solution and a liquefied gas as contents.

In the present embodiment, when ejecting the content, first, as shown in FIGS. 5A and 5B, the head 50 mounted on the engaging cylinder 23c of the upper lid 23 of the metering unit 20 is pressed against the target object. The upper lid 23 is pushed down to store the contents in the fixed amount chamber E (storing operation).
At least a part of the liquefied gas of the content stored in the fixed quantity chamber E is vaporized in the fixed quantity chamber E because it is composed of an emulsion obtained by emulsifying the aqueous stock solution and the liquefied gas. Therefore, as shown in FIG. 5c, when the pressing is loosened (release operation), the contact between the upper lid 23 and the valve seat 21 is released due to the pressure of the content in the fixed amount chamber E, and the engagement cylinder 23c of the upper lid 23 is released. When passing through the injection hole 50a having a diameter smaller than the inner diameter, a turbulent flow is generated and a large injection sound is emitted. In this embodiment, the spring S is inserted between the bottom portion 22a of the lower plate 22 and the upper lid 23 in order to promote the separation of the upper lid 23 from the valve seat 21 during the releasing operation. A spring S may be provided between the mounting cup 13 and the lower end of the upper lid 23, between the mounting cup 13 and the bottom portion 22a of the lower tray 22, or between the mounting cup 13 and the flange portion 21c of the valve seat 21. Also, if the pressure of the contents in the fixed amount chamber E is sufficient, it may not be provided. In addition, a ring-shaped projection 15e may be provided on the outer periphery of the stem 15 so that the content in the fixed amount chamber E does not leak from the fitting portion of the stem 15 and the valve seat 21.

In this way, the pressurized and sealed content is once introduced into the metering unit 20 (quantity chamber E) having a larger volume than a general injection passage, and at least part of the liquefied gas is vaporized and then released. Thus, since a sounding means (sounding mechanism) that emits a loud sound at the time of injection is provided, a feeling of use can be obtained as compared with the case of simply injecting. In addition, the content in the metering unit 20 is vigorously ejected from the ejection hole 50a, gives a strong stimulus to the skin and the scalp, and a feeling of satisfaction is produced, which leads to suppression of overuse.

The following is a detailed description of the contents.
The content is an emulsion obtained by emulsifying an aqueous stock solution containing a surfactant and a liquefied gas. The aqueous stock solution contains a surfactant in water and is emulsified with the liquid of the liquefied gas in the aerosol container 10. It forms an emulsion, and when sprayed to the outside, forms a foam by the vaporizing action of the liquefied gas or forms a frozen substance.

The content of the aqueous stock solution is preferably 10 to 70% by mass, and more preferably 15 to 60% by mass in the aerosol composition. When the content of the aqueous undiluted solution is less than 10% by mass, the emulsification with the liquefied gas becomes unstable and it is difficult to obtain a desired injection state (injection sound or momentum of injection), and when it is more than 70% by mass. Is because it is difficult to obtain a large jet sound.

The surfactant emulsifies the aqueous stock solution and the liquefied gas in the aerosol container 10, and at the same time when the content is introduced into the metering unit 20, at least a part of the liquefied gas is vaporized in the content and the metering unit 20. When the contents inside are jetted to the outside, a loud jet noise is easily emitted. Examples of the surfactant include polyoxyethylene sorbitan fatty acid ester, polyglycerin fatty acid ester, polyoxyethylene alkyl ether, nonionic surfactant such as polyoxyethylene hydrogenated castor oil, silicone-based surfactant and a mixture thereof. can give. The content of the surfactant in the aqueous stock solution is preferably 0.1 to 20% by mass, more preferably 0.5 to 15% by mass. When the content of the surfactant is less than 0.1% by mass, the emulsification becomes unstable and it is difficult to obtain a desired jet state. This is because if the amount is more than 20% by mass, the feeling of use such as stickiness tends to be poor and it tends to remain in the quantitative unit 20.

The water is not particularly limited, such as purified water and ion-exchanged water. The content of the water is preferably 50 to 99 mass% in the aqueous stock solution, and more preferably 60 to 97 mass %. When the content of water is less than 50% by mass, the emulsification with the liquefied gas becomes unstable and it is difficult to obtain a desired injection state, and when it is more than 99% by mass, it becomes difficult to contain components other than the surfactant. This is because. The aqueous undiluted solution may contain active ingredients such as scalp washing and sebum suppression, alcohol, oil, powder and the like depending on the use and purpose of the product.

The liquefied gas becomes a liquid in the aerosol container 10 and is emulsified with the aqueous undiluted solution. At least a part of the liquefied gas is vaporized when introduced into the metering unit 20, and in the passage when ejected from the metering unit 20 to the outside. When a turbulent flow is formed and ejected from the ejection hole 50a, a large ejection sound is emitted. Examples of the liquefied gas include liquefied petroleum gas, dimethyl ether, hydrofluoroolefin, and a mixture thereof. The content of the liquefied gas in the aerosol composition is preferably 30 to 90% by mass, more preferably 40 to 85% by mass. When the content of the liquefied gas is less than 30% by mass, it is difficult to obtain a large injection sound, and when the content of the liquefied gas is more than 90% by mass, the emulsification with the aqueous stock solution becomes unstable and the desired injection sound is difficult to obtain. Is.

The contents of the above composition are obtained by mixing the aqueous stock solution and the liquefied gas by, for example, vibrating the aerosol container 10 while the container body 11 is filled with the aqueous stock solution and the liquefied gas and the valve 12 is fixed. It can be emulsified.

The representative embodiments of the present invention have been described above, but the present invention is not limited to the above embodiments, and various modifications can be made within the scope of the present invention. For example, in the embodiment of FIGS. 1 to 3, the tilt type valve may not be used depending on the direction of elastic deformation of the pressing protrusion 32b. That is, in the above-described embodiment, the tilt type valve is used to easily release the elastic deformation. However, if the elastic deformation can be released only by pushing, such as the pressing protrusion 32 is relatively flexible, it is not always necessary. It is not necessary to use a tilt type valve. Further, the embodiment of FIG. 5 may be combined with the embodiment of FIGS. Furthermore, a resonator may be separately attached, or a mechanism for causing the ejection members 30, 40 and the head 50 to resonate (resonate) may be provided.
